Abstract An anticollision stroboscopic aircraft beacon employs an annular flash tube lamp and a circularly continuous reflector. The reflector is divided into separate upper and lower portions. The lower reflector portion is positioned in close proximity to the lamp and forms the ionizing electrode for the lamp. The reflector portions form a parabola in section, and the lamp is located at the focus of the parabola to direct the light outwardly with the most intense portion of the pattern in a horizontal plane covering 360*. A gap or space between the upper and lower portions of the reflector permits light from the back side of the lamp to pass through the gap and contribute to the output intensity on the opposite side.
A stroboscopic anticollision beacon for aircraft or the like comprising a mounting base, an upstanding cup-shaped lens mounted on said base, a capstan-shaped reflector within said lens having an upper half mounted on said lens and a lower half mounted on said base and defining with said upper half a tranSversely open space therebetween, and a gas discharge lamp encircling said reflector between said upper and lower halves in the region of said open space so that light from the inside surfaces of the lamp is free to pass transversely through said space.

A stroboscopic anticollision beacon for aircraft or the like comprising a mounting base, an upstanding cup-shaped lens mounted on said base, a capstan-shaped reflector within said lens having an upper half mounted on said lens and a lower half mounted on said base and defining with said upper half a tranSversely open space therebetween, and a gas discharge lamp encircling said reflector between said upper and lower halves in the region of said open space so that light from the inside surfaces of the lamp is free to pass transversely through said space.
Claim 3
Dependent Claim
57 words
The beacon of claim 1 in which said lower reflector half is made of electrically conductive material and is contiguous with said lamp over a substantial extent thereof, and an ionizing circuit for said lamp having an electrical connection with said lower reflector half reflector that said lower reflector half forms the ionizing electrode for said lamp.
Claim 4
Dependent Claim
30 words
The beacon of claim 1 in which said lower reflector half defines with said base a closed annular space in which electric circuit components and potting compound may be received.
Claim 5
Dependent Claim
32 words
The beacon of claim 1 in which said upper and lower reflector halves define a parabolic surface of revolution in which said lamp is located generally at the loci of focus thereof.
